Application led September 8, 1916. Serial No. 119,072.

To all whom 'it may concer/n.'

Be it known that l, WILLIAM S. Burnin, a citizen of the United States,residing at Chicago, in the county of Cool; and State of lllinois, haveinvented new and useful lmprovements in TWindow-Sashes, ofwhich thefollowing is a specification.

This invention relates to windows and particularly to the sashes forwindows which, through the use of this invention, may be easily removedfrom the window frames.

The object of the present invention is to provide a window frame with asimple, inexpensive, and reliable means for releasing both the upper andlower sashes from the grooves in the sides of the window frame, and fromthe sash cords without having to withdraw nails or screws when repairs,cleaning or painting is required.

Another object of the invention is directed to the attachment of thesash cords to the sash, by means of hook-like terminals on the outerends of the cords that engage with the under side of the sashes and areheld in engagement therewith when the sashes are in operative position,means being provided to catch the hooked ends of the terminals and holdthe sash cords when the sashes are removed.

Other details of construction will be set forth in the followingspecification and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a window complete provided with theimprovement, a portion of the window frame being broken away;

Y Fig. 2 is a vertical longitudinal sectional view of the window frame,the edges of the sashes being shown in elevation, and

Fig. 3 is a detail perspective view of one corner of a window sashshowing the sash cord holding means.

In the drawing, 10 indicates the window frame as a whole, 11 the jambsand 12 the window sill. As usual, the jambe 11 are each provided on itsinner face with two parallel grooves 13, 111, formed by an inner moldingstrip 15, an outer strip 16 and a parting bead 17. Usually these threestrips are continuous from the top of the window to the sill 12, but forthe purpose of the present invention, the molding strip 15 and partingbead 17 are each formed of two longitudinal sections, divided a fewinches above the meeting rails of the lower sash 18 and the upper sash19 when the window is closed and connected as shown by a lap joint 2 Theupper sections 21 of each molding strip 15 and parting bead 17 arefastened in the usual manner to the window frame by the use of nails.rfhe lower section 22 of each molding strip is held in a straight linewith the upper section by means of a swinging latch or tongue 23,pivoted on the upper section 21 and adapted to swing over and retain thelapped end 20 of the lower section 22. Projections of any kind may bepro vided on the lower section22 to enter freely into recesses in the jamb 11 and sill 12 to prevent the section slipping. Instead of theswinging latch 23, any other desirable form of fastening may beemployed.

The lower section 2l of the parting bead 17 is sustained in the samemanner as sec- Jtion 22 and maintained in place by a latch 1n the sidesof each sash are formed grooves 26 that extend longitudinally from topto bottom of the sash. rlfhese grooves form seats for metal strips 2i"that lie flush with the sides of the sash and permit the sash to slidefreely7 in the window frame 10. Each metal strip 27 is preferably madenearly as long as the groove 2G and has an eye 28 in its upper end towhich one end of the sash cord 29 is fastened. The lower' end of eachstrip is bent at a right angle toward the sash to form a foot orhook-like projection 30 that enters re ess 31 in the bottom of the sash.A cross notch 32 is made in the bottom rail of the lower sash 18 at eachside which intersects the recess 31 of the same side, each notch beingof such size that a swinging or other form of catch 3?), seated in adepression 34- in the window sill 12, can enter said notch and passabove the foot 30 of the metal strip 27. Similar cross notches, shown indotted lines l? ig. 2, are made in the under side of the parting rail ofthe upper sash 19.

lli/'ith a window equipped with the means described, the sash may beeasily removed and replaced without much effort. rl`he lower sash, ifraised, is drawn down into closed position and the catches 33 on thewindow sill engaged with the hoolelile projections or feet 30 on themetal strips 27. rllhe catches 23 on the upper sections of the moldingstrips 15 are then disengaged from the lower sections and the latterremoved l'the strips 27 from the grooves 26 in the sides ofV the sash.The upper sashis removed in the same way after lowering it bydisengaging the catches 25 from the lower seovtions 24 of the partingbead and remove the same, then slip the catches over the inturned endsof the metal strips 27.

It is to be understood that while the oonstruction shovvn and describedis the best form at present known, various changes in the constructionand arrangement may be made withoutvdeparting from the principles oftherinvention.

I claim:

l. The combination with a window frame and a sash slidable therein, saidsash having longitudinal grooves in its side edges; of sash cordattaching strips removably itted in the grooves iiush with the edges ofthe sash, said'st'rips having angular lower ends extending, beneath thebottom rail of the sash, and means on the window iraine engageable withsaid angular lower ends of the strips for holding said strips stationaryrelative to the sash.

2. The combination with a window frame and a sash slidable therein, saidsash having longitudinal grooves in its side edges; oi sash cordattaching strips removably litted in the grooves iiush with the edgesoi' the sash, said strips having angular lower ends extending beneaththe bottom rail of the sash, and catches pivoted on the window sill andengageable with said angular lower ends of the strips for holding thesame stationary relative to the sash.

3. The combination with a window frame and a sash slidable therein, saidsash having longitudinal grooves in its side edges; of sash cordattaching strips removably fitted in the grooves flush with the edgesoit the sash, said strips having angular lower ends extending beneaththe bottom rail o'f the sash, and catches pivoted on the window sill andengageable with said angular lower ends of the strips for holding thesaine statimiary relative to the sash, that portion of the bottoni railof the sash which is engaged by the angular lower ends of the stripsharing recesses which are entered by the catches when the saine areswung to engage said angular lower ends of the strips.

In testimony whereof I aiix inv signature.

WILLIAM s. BURKE.
